Revisiting the two-body problem in Yukawa gravity and in a gravitational extension of the Buckingham potential
E. A. Gallegos, R. Perca Gonzales, J. F. Jesus
We revisit the Keplerian-like parametrization of the two-body problem in Yukawa gravity studied in the literature. Some inconsistencies, which spoil Bertrand's theorem, observed in…
Kinematic reconstruction of torsion as dark energy in Friedmann cosmology
A. M. Vicente, J. F. Jesus, S. H. Pereira
In this paper we study the effects of torsion of space-time in the expansion of the Universe as a candidate to dark energy. The analysis is done by reconstructing the torsion funct…
Acceleration in Friedmann cosmology with torsion
S. H. Pereira, R. de C. Lima, J. F. Jesus +1
A Friedmann like cosmological model in Einstein-Cartan framework is studied when the torsion function is assumed to be proportional to a single function coming just from the…
cosmology induced by a slowly varying Elko field
S. H. Pereira, S. S. A. Pinho, J. M. Hoff da Silva +1
In this work the exact Friedmann-Robertson-Walker equations for an Elko spinor field coupled to gravity in an Einstein-Cartan framework are presented. The torsion functions couplin…
